Contacts - strange number assignments

So, I've seen this before, but forgot where. I think it was about contact linking or something. For now, to see this, go to Barcode Scanner and hit the menu button. From there, click Send and choose Contacts. It will give you the list below as the option to choose from.

I know that those numbers are my contacts' information, but is there a way to display them in a way that is more usable? It's pretty much useless this way and I've seen it once before when trying to set up my phone - I remember being frustrated by it, too.

Any clues as to what it is and how it works? Is there a way to decipher the numbers without clicking on each one?
